Title: Method for forming compound oxide superconducting thin film
Inventor: NAGAISHI RYUKI
IPC: C23C14/28
Filed: 1992-01-10
Abstract: PURPOSE:To form the subject thin film of a large area by arranging the central shaft of blooms generated from a target and the central shaft of a substrate on which a thin film is deposited so as not to coincide and carrying out the film-forming treatment while rotating the substrate with the shaft as the center. CONSTITUTION:A target 7 such as a Y-based compound oxide sintered compact is set on a target holder 3 and a substrate 6 such as MgO single crystal is set on a substrate holder (2a) in a vacuum vessel 1. Both are then repeatedly irradiated with laser beams from a laser device 5 through a transparent window 4 and blooms emitted from the target 7 are deposited on different regions on the substrate 6 while simultaneously rotating the substrate 6 heated to a prescribed temperature to form a continuous compound superconducting thin film of a large area.

IPC: H01L21/331
Filed: 1995-02-09
Abstract: PURPOSE: To lighten the electric field concentration in and around an emitter, and besides, put a bipolar transistor in such structure that it does not change the current amplification factor by implanting phosphorus ions into a base diffusion layer, and relaxing the field concentration of the carriers of the base diffusion layer in the region where the emitter does not exist in and around the emitter. CONSTITUTION: First an n-type buried diffusion layer 101, and next an n-type epitaxial layer 102 are produced on a p-type silicon substrate 100. Next, a base formation area 103 and a collector formation area 104 are separated from each other, using a separation oxide film 105. Next, a resist pattern 106 is made so that the surface of the p-type silicon substrate 100 other than the base formation area 103 may not receive ion implantation. Furthermore, B<+> ions are implanted, with the resist pattern 106 and the field oxide film 105 as masks so as to form a base diffusion layer 107. Next, using the same resist pattern 106, P ions are implanted. Here, the energy of P is selected so as to bring projection range to be on the same level as that of the energy of B.

Title: Waveform equalizing device
Inventor: SHIMADA TOSHIYUKI
IPC: H03H21/00
Filed: 1984-02-08
Abstract: PURPOSE:To improve the converging and stability performance by reproducing a comparatively stable data clock signal from an equalizing output signal and using the data clock signal to provide a more accurate reference signal where the shift of zero cross point of the equalizing output signal is suppressed. CONSTITUTION:The adaptive algorithm by means of the least square error method is realized except the generation of a reference signal in the basic operation of the titled device. Delay lines 10 and 11-1-11-5, in this case, correct the time delay for the generation of the reference signal by retarding equally a V0 and each tap output. When the equalization is incomplete, a zero cross detection signal is a signal inverted at a phase different from that of an original signal by means of the shift of zero cross point of the equalized output. When the shift amount of the zero cross point is not extremely larger in this case either, a discriminating output signal is operated invertingly at the phase of the trailing edge of the regenerated data clock just after the signal inversion of the zero cross detection signal takes place in order than the regenerated data clock signal represents a correct phase. Moreover, the regenerated data clock signal is a signal suppressing the phase fluctuation of the data clock of the equalized output signal by a phase synchronism circuit 8 and gives a comparatively stable phase.

Inventor: KAMAYA NAOKI
IPC: H04N13/02
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a stereoscopic video photographing recording and reproducing device with which a three-dimensional (3D) stereocopic image can be easily photographed, etc., as well by arranging two video cameras separated only for the width between eyes. SOLUTION: A stereoscopic video photographing device to be used for a stereoscopic video photographing recording and reproducing device 1 is composed of two video cameras 2R and 2L. Concerning these two video cameras, a zoom lens is used for an image pickup lens 2a of one video camera 2R, and a fixed magnification lens is used for an image pickup lens 2a' of the other video camera 2L. When photographing an ordinary two-dimensional (2D) image, wide and telescopic extended images are simultaneously photographed and can be arbitrarily switched. As a result, not only at the time of photographing a 3D image but also at the time of photographing a 2D image, photographing is enabled while fully effectively utilizing two video cameras 2R and 2L. Besides, since so-called electronic zooming is performed for zooming at the time of 3D photographing, any complicated mechanism is no required.

Filed: 1980-02-25
Abstract: PURPOSE:To obtain very intelligible compact electronic equipment by the constitution wherein a timing system having an additional different function follows the timing system of 12hr and 24hr having a clock function. CONSTITUTION:A count up signal (f) becomes carrying up input from a minute in a clock counter and becomes a correcting signal from a control circuit in an alarm counter. Signals a-d are binary output signals to be sent to a decoder. Only an output signal (e) becomes a morning or afternoon output in 12hr system and becomes the highest bit output in a 24hr system. When the potential of the a 12hr indicating signal (g) is high, transmission gates 30-34 are turned on, and the 12hr signals appear at (a)-(e). When the potential of (g) is low, transmission gates 35-39 are turned on, and 24hr signals appear. In this constitution, the different timing system with an additional function can follow the timing system with a clock function, and very intelligible compact electronic equipment can be obtained.

Filed: 1995-02-10
Abstract: PURPOSE: To obtain a polyethylene sheet with a laminated primer which has a good shape retention property and is free from heat deformation by heating the surface of a primer applied on the polyethylene sheet with a hot roll and cooling the back of the sheet with a water-cooling roll. CONSTITUTION: In the production of a polyethylene sheet 1, first a primer 2 for polyethylene is applied on the sheet 1 with a spray 3.

The hot roll 5 and the water-cooling roll 6 are rotated to transfer the sheet 1. In other words, the surface of the primer 2 applied on the sheet 1 is heated, and simultaneously the back of the sheet 1 is cooled. In this way, the softening of the sheet 1 associated with heating is restricted to the surface layer, preventing the deformation of the polyethylene sheet 1.
